Advantages of Ball Screws

Highly Efficient

Ball screws are more efficient than other types of screws, boasting 90% efficiency in comparison to a lead screw’s 20-80%. This means that ball screws are able to convert more of their rotary motion to linear motion more quickly than other types of screws.

Accurate

Ball screws are also known for their accuracy. They enable high-precision positioning due to their low return clearance and high rigidity.

Lessen Friction

The ball bearings of a ball screw serve to reduce friction as the nut moves along the shaft of the screw. This results in less wear to the device in addition to a longer lifespan.

Stability

Ball screws can handle larger loads without sacrificing stability, making them reliable in demanding environments.

Durability

Hardened steel balls ensure a long lifespan and reduced wear over time.

Components of Ball Screws

01/

Threaded shaft: The threaded shaft is the core component of the ball screw. It is made of high-strength steel and has a precise thread profile that the ball bearings move along.

02/

Nut: The nut is the housing for the ball bearings. It is typically made of steel and is designed to minimize friction between the ball bearings and the threaded shaft.

03/

Ball bearings: The ball bearings are what enable the nut to move along the threaded shaft. They are typically made of steel or ceramic and are designed to minimize friction and wear.

04/

End supports: The end supports are used to hold the ball screw in place and support the load. They are typically made of cast iron or steel and are designed to minimize deflection and vibration.

05/

Recirculation system: The recirculation system allows the bearings to move continuously between the grooves on the screw.

06/

Seals: Seals shield the ball bearings and the recirculation system from external contaminants such as dust. This helps to keep the bearings lubricated, reducing wear and friction.

Installation method and usage precautions of ball screws

Installation method

One end is fixed, and the other is supported. This is the most common installation method, suitable for medium-speed to high-speed rotation, and the accuracy level can reach medium precision and high precision;

Fixed at both ends, only suitable for medium-speed rotation and with high precision;

One end is fixed, and the other is free, suitable for low-speed rotation and medium precision.

Precautions for Using Ball Screw

When installing: Be careful not to damage the tooth surface of the screw; after the screw is purchased, the nut and screw are together, so when installing, pay special attention. First, at both ends. Tie a tie or install a limit block. Do not separate the nut and screw. Once separated, it will be challenging to install them. If it is accidentally separated, do not force yourself to install it.

Lubrication: There is metal friction between the ball and the screw, so lubricating oil or grease must be added between the two. Otherwise, the service life will be reduced; the general adding methods include manual and automatic refueling. Manual refueling is performed regularly by workers. Oil filling and automatic oiling require an automatic oiling system;

Dustproof: Ball screws are the same as rolling bearings. When mixed with debris, water, or cutting fluid, the wear will increase, sometimes leading to damage. When designing, pay attention to the dustproof ness of the screw;

When the eccentric load phenomenon occurs:It will directly affect the life and noise of the screw and is accompanied by a rough operating feel. If the smoothness of the screw is different when it is unloaded and after assembly, in addition to paying attention to the accuracy of the screw itself, most of them is the phenomenon of eccentric load caused by poor combination accuracy.
